Is this the "Jam Cruise" that you're talking about? Because if it is, it was a ship filled with mainly hippies, a ton of bands with tents set up throughout the ship and the bands played all night long. Point is, if they only got 11 people, I absolutely guarantee that they didn't catch 100's of other people who also had something on them. That's the scene with the jam bands and it was a Jam Cruise.
